IMPROVEMENT IN PENCIL-ATTACHMEfi T 'I'O COMPASSES.

The Schedule referred to in these Letters Patent and making part of thesame.

To allwho'm it may concern.-

Be it known that I, CLARK L. TYLER, of Ithaca, Tompkins county, NewYork, have invented an Improvement in Attaching Pencils to Dividers, ofwhich the following is a specification.

My object is to make a holder which shall be selfadjustable to thepencil, and also to the leg of the dividers.

Figure 1 is a side view of my pencil-holder;

Figure 2, a section thereof;

Figure 3, a view of the internal variable block; and

Figure 4, sections of this block, and its axis.

In fig. 1, A and B aretwo tubes, one for the pencil and the other forone leg of the dividers, connected the web between the'two tubes, andsecured by the pin in the slot G", fig. l, a pencil put in one of thetubes will bear on one of the parts of the block; and when the leg ofthe dividers is thrust into the other tube, the thrusting in causes thevariable block to act, and to hold both pencil and dividers; theoscillation of one ,of the said parts of the block, allowing anadjustment to the varying taper of the compass- ]eg, and the lateralplay of the compound block, by its axis in the transverse slot, allowingits adjustment to difi'erenhsizad pencils.

The uses and advantages of my invention are apparent to those skilled inthe art to which it appertains. Y

' Claim.
